About the Project

Wikipedia describes special functions as:

particular mathematical functions that have more or less established names and notations due to their importance in mathematical analysis, functional analysis, geometry, physics, or other applications. The term is defined by consensus, and thus lacks a general formal definition ...

This library implements those special functions required to support statistical distributions.

Built With

• float-features
• numerical-utilities

Getting Started

To get a local copy up and running follow these steps:

Prerequisites

An ANSI Common Lisp implementation. Developed and tested with SBCL and CCL.

Quicklisp Installation

(ql:quickload :special-functions)

Manual Installation

1. Clone the repository

   cd ~/quicklisp/local-projects &&
   git clone https://github.com/Lisp-Stat/special-functions.git
   

2. Reset the ASDF source-registry to find the new system (from the REPL)

   (asdf:clear-source-registry)

3. Load the system

   (ql:quickload :special-functions)

Usage

Obtain a log-gamma value

(spfn:log-gamma -9.99999237060546875d0) ;=> -3.3208925610275326d0

For more examples, please refer to the Documentation.

Roadmap

See the open issues for a list of proposed features (and known issues).
